Terminal, radio communication method, and base station

Abstract

A terminal according to one aspect of the present disclosure includes a control section that performs a measurement on a Doppler shift of a channel state information (CSI)-reference signal (RS) and determines channel state information (CSI) based on the measurement, and a transmitting section that transmits a reporting of the CSI. According to one aspect of the present disclosure, the measurement/reporting on the impacts of movement can be properly performed.

1 . A terminal comprising:
 a control section that performs a measurement on a Doppler shift of a channel state information (CSI)-reference signal (RS) and determines channel state information (CSI) based on the measurement; and   a transmitting section that transmits a reporting of the CSI.   
     
     
         2 . The terminal according to  claim 1 , wherein
 the measurement is based on a configuration of a resource set of the CSI-RS for the Doppler shift.   
     
     
         3 . The terminal according to  claim 1 , wherein
 the CSI includes information related to the Doppler shift or a time domain correlation.   
     
     
         4 . The terminal according to  claim 1 , wherein
 a plurality of resources of the CSI-RS is accompanied by at least one of a same frequency domain resource and a different symbol.   
     
     
         5 . A radio communication method for a terminal, comprising:
 performing a measurement on a Doppler shift of a channel state information (CSI)-reference signal (RS) and determining channel state information (CSI) based on the measurement; and   transmitting a reporting of the CSI.   
     
     
         6 . A base station comprising:
 a control section that determines a configuration of a measurement on a Doppler shift of a channel state information (CSI)-reference signal (RS); and   a transmitting section that transmits the configuration.
